SHOE HEATER.

Application filed December 12, '1921. Serial No. 521,758.

To oZZ who/m it may concern.'

Be it known that l, l/VILLIAM H. BAYNARD, a citizen of the United States; residing at Quincy, in the county of Norfolk and State of Massachusetts, have invented new and useful improvements in Shoe Heaters (Case A), of which the following is a specification.

fn the manufacture of shoes it 1s common practice to insert stiflening members between the upper and lining at certain parts of the shoe for example, at the toe. These 1ne1n bers are often composed of sheet material treated7 impregnated, or coated with asphaltic or resinous materials which may be softened by the application of heat7 or heatand moisture, so t-hat they may conform to the configuration of the lastI and then be allowed to harden to retain the shape imparted. ln practice it is usual to soften these stiffeners twice, first, after the portions of the shoe have been assembled and beforeV the upper has been pulled over the last, and second, betweenf'the pulling over and final lasting operations.

The present invention relates to a construction more particularly adapted and de- Vsigned to effect the first heating operation. The stiffener as lassembled in the toeis substantially flat and the upper 'is attached to the Ilast only at the heel'. VThe toe portion may therefore be laid on a support where it may be subjected to heated vapor while the toe ofthe last ext-ends beneath the support.

One feature of this invention relates to the construction vof 'support by which a sheet of fabric is held beneath the shoe upper7 the V,vapor passing through the fabric.

A further1 feature relates to improved vapor producing and distributing means by which vapor is supplied to the lowerA face of the fabric. v Further features and advantageous details of construction and combinations of parts will appear from a Inore'completev description of the embodiment shown inthe draw ings in which- Figure l is a plan `of a heater partly broken away.

'Figure Ll isa diagram of the electrical wiring.

Fefeirig to these figures at l is indicated a base in the form of shallow pan for supporting the heater. rlfhe heater coinprises an elongated receptacle 2 having a comparatively ceep trough portion 3 along one side and a shallow basin portion a er;n tending parallel thereto. rlfhe trough porn tion 3 is substantially circular in cross section and extending therethrough and nearly filling this portion is a pipe 5 inade fast at its ends in the end walls of the receptacle to malte a fluid tight jointt`icrewith. .Substantially centrally of the length of this receptacle is a lateral extension 6 formed as a general triangularly shaped open topped pan having a rounded apex. rlhe side walls of this pan are formed by a marginal upwardly extending flange V7 .to which is inade fast at the apex of the pan a bracket 8 Carrying at its top a. support 9 having an upwardly er;n tending marginal flange l0. As shown this flange is formed ring shape and is intended to serve as a retainer for the lower end of a similarly shaped water reservoir from which water may be led into the pan. A pipe ll passes up through the bottom of the pan at one 'end and at its other end up through the bottom of the receotacle 2 opening beneath the pipe By this means the water is conducted from the pan to the trough portion of the receptacle.

The basin portion 4: is formed with a base member l2 which extends toward the top of the trough 3 at a gradual upward inclina tion, while the outer edge of the portion l? is turned upwardly as shown at 13. The rear wall of thetrough portion extends upwardly considerably above the member l2 as shown at A, and extending over the wall la and the outer edge 13 of the basin is a fabric of canvas or the li`:e l5. ri-he forward end of this canvasis turned under tl e base plate l2 and is formed with a looped elge through which passes a retaining rod 1G which is supported in any suitable manner preferably at its ends in portions of the member 2. rhe opposite end of the fabric is looped about a bar i7 which may be passed beneath a pair of lu i8 ertendufy outwardly and se i rearwardh trom the wall l-l and through which are threaded adjusting bolts 19 which bear on the ends of the bar 17. By turning down these bolts the bar 17 may be lowered, increasing the tension` on the fabric. In order to support this fabric against undue sagging it is preferable to place therebeneath a support preferably formed of a wire lnetting or other foraminous material 20 which is curved downwardly at VVits forward edge at 2l to rest on the upper surface of the base plate l2 and at. its rear end it is bent downwardly into engagement with the upper surface of a baiile plate 22. This baille plate is positioned directly above the trough 3 and is .forwardly and downwardly inclined'so that vapor arising from the trough is directed forwardly to mingle with Vapor arising from the basin. holds the fabric out of contact with the plate 22V so that vapor may pass freely Vtherebetween.

The vapor is v.produced in the trough by meansV of any suitable form of heater, as herein sho-wn an electric heating eleinent 25 being employed. rl'his element eis- Vtends through the pipe 5 and one end is connected to a wire 26 leading to a lamp socket 27 and to a switch '28. The other end of this :heat-ing element has attached thereto' va. wire 29 which exten-ds through ya pine 4v30() positioned substantially beneath the bai' 17 and siqiported in bracket ears 3l. extending rearwardly at opposite ends of the ineinber 2; After passing through this pipe the wire 29 leads to the lamp socket l27 land switch 2S. Pit 30 is' shown a lanip held-by thesoclet. IASV shown in Figure fi the lainipV 80, is lshunted across the wires 26V 4and 29"and1 furnishes a Visible indication afs to whether or not the heater is in operation Positioned forwardly of the base member l is a vshoe support 35 which inclines up wardly laway fronithe heater. lThis support has an upwardly directed flange portion or guard 36 against which the toe end Vof thelast ina-y rest as shown in Figure 2 so that the toe of `the last may be kept out of contact with the heater and protected from ythe heat therefrom by which it ymight be liable `to Abe injured. .as shown .in Figure' 2 the toe of a shoe may be supported on the ineni'ber the last extending under the basin 2l and the upper, together with the stiliener `assembled therein, being laid von the upper face of the fabric. lf now the water in the trough be'lieated by the electric heating element `some of 'this water may boil over and ll the basin 2l. Steam arising from the trough is deflected by the plate 22 foi` waidly, and iningles with the .steam arising freni the water boiled into the basin. steam from both sources then finds its way through the fcraniinous support and the fabric to the under side of the shoe upper The support 2O A where Vit may act to soften the stitfener. rihe comparatively small water-receiving capacityof the trough causes the water to beboiled quickly so that no material delay is occasioned in starting the apparatus, while the presence of the basin serves to supply acooler vapor which teinpers the severity of the heat. The bafile plate 22 causes the Vvapors to be thoroughly mixed `and causes a substantially even distributienet the Vapor ov r the fabric so that the tempering andV softening of the slice upper is uniformly eii'ected.

Having thus described an einbodii-nentof this inif'entionit should be evident that many changes and modifications might be made therein without depart-ing from its spirit or` scope as deiined by the appended claims.
